Florets bisexual, zygomorphic, transitional between actinomorphic and ligulate, often villous; anther apical appendages apiculate to caudate, tails laciniate, long, acute, tails connate; style bilobed, branches appressed, dorsally pubescent reaching the bifurcation point, hairs acute.
Florets bisexual, corolla actinomorphic, deeply five-lobed, tube narrow, gradually dilated into a limb to sub-campanulate, lobes coiled; anther apical appendages acute to acuminate, tails papillose; style bifid, branches appressed, apically pubescent and also hairs in a subapical ring, hairs acute.
Flowers 5-merous, actinomorphic, the calyx lobes rather small, [+ or -] persistent and the corolla polypetalous, rotate, glabrous.
Flowers usually 4-7(-9)-merous, actinomorphic or slightly zygomorphic, sometimes variably reduced and wind pollinated, with a distinct calyx and corolla or perianth parts [+ or -] undifferentiated, pendulous to erectly held.
Flowers usually showy, dioecious, rarely monoecious, usually actinomorphic, rarely dimorphic (Hockinia); pollination by insects.
Flowers solitary in leaf axils, actinomorphic and dioecious.
Corolla symmetry: actinomorphic
= 0; zygomorphic = 1.
Similarities between flowers of Adenanthemum Conwentz and Itea include that the flowers are hermaphroditic, pedicellate, have a pentamerous and actinomorphic
perianth with distinct whorls of sepals and petals, a valvate corolla, a haplostemonous androecium with antesepalous stamens, dorsifixed anthers with introrse dehiscence, a superior ovary (ovary position is variable in Itea), two fused styles, and a single, capitate stigma (Conwentz, 1886; Kubitzki, 2007a).
6 m tall, the rosettes actinomorphic
to slightly zygomorphic in mature plants, 40-80 cm diameter.
Isolation and sequence analysis of two CYC-like genes, SiCYCIA and SiCACIB, from zygomorphic and actinomorphic
cultivars of Saintpaulia ionantha (Gesneriaceae).
1985) and Kubitzki (1987), we consider cyperoid flowers to be derived from a typical trimerous, actinomorphic
, diplostemonous, monocot flower with a superior syncarpous pistil (e.
He pointed out, however, that several genera of Mutisieae differ in having actinomorphic
or ligulate corollas and ecaudate anthers (the last feature in some genera of Barnadesiinae).
Florets isomorphic, bisexual, rarely the marginal ones female with staminodes, corolla actinomorphic
, tubular-funnelform to subcampanulate, shallowly to deeply five-lobed; anther apical appendages acute, tails smooth to papillose, filaments smooth to papillose at the base; style bifid to bilobed, branches dorsally papillose.
Florets dimorphic, bisexual; marginal florets with corollas bilabiate, outer lip, expanded; central florets with corolla actinomorphic
, tubular-campanulate, deeply five-lobed; anther apical appendages apiculate, tails papillose; style bifid, branches dorsally smooth.
Florets bisexual, corollas actinomorphic
, tubular-funnelform to sub-campanulate, deeply five-lobed, exceptionally bilabiate; anthers mostly exserted, apical appendages acuminate, tails long, smooth to papillose, free to those of adjacent anthers often connate; style cleft into two short, bilobed branches, the branches erect, apically rounded, dorsally rugulose to papillose with the branch apex often smooth and the papillae extending beyond the bifurcation point onto the shaft, occasionally styles bifid, branches recurved and dorsally smooth.
